COMBINED LETTER SHEET AND ENVELOPE.

T0 all whom it may concern:

Be it known that I, WILLIAM G. GRUBER, a citizen of the United States, residing in the city of Milwaukee, county of Milwaukee, and State of lVisconsin, have invented certain new and useful Improvements in Combined Letter Sheets and Envelopes, and do declare the following to be a full, clear, and exact description thereof, such as will enable persons skilled in the art to which the invention pertains to make and use the same, reference being had to the accompanying drawings for disclosure as to the arrangement of certain of the details involved in my invention.

My invention relates to a letter sheet for use in business or other correspondence, and is so treated that the usual enclosing envelope is dispensed with, the superscription on the sheet serving the purpose of the address to the person for whom the communication is intended.

One object of the invention is the production of a letter sheet Which is so n1anipulated that the name and address of the party and the body of the communication are written with a single insertion of the sheet in the typewriting machine, but in the completed communication, the address will appear upon the front face of the sheet after being folded and sealed, While the message or body of the communication will appear upon the other, the letter sheet being so folded for transmission in the mail that the message is completely concealed from inspection by unauthorized persons.

A further object resides in the production of a letter sheet designed for the purpose of correspondence, which shall remain intact, and thus preserve in its single entity, the communication, the name and address of the person to whom the message is directed, and the stamps or marks usually applied by the postal authorities to mail matter of this class.

In common practice, the enclosing envelope is usually discarded, and evidence which at some later time might be of value is destroyed. But by the use of my invention, the facts are established, and the necessity of proving the act of mailing is obviated, should later conditions render it desirable to do so.

An exposed corner of the folded sheet or packet is turned under, and to this corner portion is applied an adhesive on both of Specification of Letters Patent. putgntgd ,A g 2g 1922 Application filed September 27, 1919. Serial No. 326,961.

ter sheet, properly addressed and ready for mailing, after placing the customary postage stamp thereon; and

. Figure 3 is a reverse view of the same.

In the present case the letter sheet composed of a business letter head A, is folded on the line 1, parallel with the top margin a thereof, so that such margin will approach the space upon which the date line is usually written. The sheet is then inserted in the typewriting machine, and the name and address ofthe person for whom the communication is intended as well as the message (y), are written line by line as the sheet is progressively passed through the machine, the name and address appearing on the back of the sheet, while the message is on the face thereof.

Upon completion of the message, the sheet is withdrawn from the machine, and the folded upper margin is opened out so that the sheet lies flat. It is then folded on the vertical line 2, and then on the line 3, which it will be observed, is slightly below the mid length of the sheet, the lower portion I), being folded on the body of the sheet at thesaid line 3. In such folding on the line 3, the lower margin is caused to lie parallel with but just below the line 1. The top margin a is now folded, on line 1 over the portion 6. The sheet is turned over and folded on the line 4, the sheet again being folded on the line 5, so that the marginal portion 0, rests upon the portion previously folded on line 4c. The corner of the marginal portion 0, is inserted in pocket (Z, formed by the portion a. The folding on line 2 of the sheet provides the means whereby the inverted seal hereinbefore referred to is produced. This inverted seal is formed at the portion indicated 7", and is constituted by folding the upper right hand corner of use the sheet after first folding on the line 2, to double the paper at the seal, adhesive being applied to both sides of the folded corner to create the said inverted seal e. After folding the sheet in the manner described, one side of the inverted seal is caused to adhere to the opposed portion of the sheet. In opening the comunication, the seal 6 is out along the folded line of the corner, so that the opposite side of the gumined seal is in position for re-sealing the communication when desired. By folding on the line 2, a perfect closure for the communication is effected, so that the contents cannot be inspected, by partially separating the folded arts. i p The projecting corner e,-of the marginal portion a is folded as indicated in Figure 3, and to this corner will be applied an adhesive substance onboth sides, one of which may be used toseal the -comuni cation by means of the inverted seal thus provided. By slitting the corner 0, at the'line of its fold, the communication may be opened for inspection by the party addressed, and the sheet will be found to be intact, except for the triangular cut 7, at the top margin of the sheet and it: may be re-sealed by moistening the unused gummed side of theinverted seal.

It will thus be seen that the communication, and the address and the postmarks, will be in a condition which will enable it to be filed and preserved intact, and that the sheet will exhibit all of the proof which would be useful .in determining any questions respecting its identity which might thereafter arise.

The exact method of folding described need not be followed in carrying out the purposes of my invention. T 1e proportions of they folded parts may be varied without departing from the spirit of the invention.

Having thus described my invention, What I claim and desire to secure by Letters Patent is:

A letter sheetfor purposes of communication, inwhichthe message appears upon one side of the sheet and the superscription upon the reverse side of the top margin thereof, the right margin of the sheet being folded on the sheet and thelower part of the sheet over the message so as to conceal the latter, the lower edge 'ofsuch lower part resting on the sheet at a line somewhat removed from the top edge thereof, the top margin being folded over the said line so as to expose the superscription, the side margins folded into operlapping position, with the said top mar in forming a band around one end of the completely folded sheet, one end of the said band being inserted. in the poclretformed'by thesaid band in the other end thereof, anc the closure being completed by an inverted seal constituted by a double folded corner of the overlapping top marginal portion. 1 M

In testimony whereof, I have signed my name at Milwaukee this 19th day of September, 1919. r
